lWHEAT AND FLouR SCALE.

SPECIFICATION forming -part of Letters Patent No. 277,292, dated May 8,1883.

' Application filed June 10, 1882. (No model.)

To all whom it may concern:

Beit known that I, GEORGE M. KNIGHT, of Adrian, in the county ot'Lenawee and State of Michigan, have invented new and usel'ulImprovements in a Wheat Scale and Gage; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeinghad to the accompanying drawing, which forms a part of thisspecilication.

The nature of this invention relates to certain new and usefulimprovements in a device for the purpose ot determining, Withoutmathematical calculation, and automatically, the value of wheat iniiour; and the invention consists in the construction and operation of ascale, by means ot' which, the quantity and quality of the wheat beingdetermined, the weight ot flour to be exchanged for said wheat isimmediately indicated, as more fully hereinafter described. f

In the accompanying drawing my inven` tion is shown in plan, wherein Arepresents a scale indicating the full weight ot' the wheat. Brepresents a scale indicating the weight ot' flour to be given inexchange for such hwheat when the latter tests up tovthe highest grade,or sixty pounds to the bushel. C represents a scale indicating the sameas the scale B when the wheat tests only fifty-nine pounds to thebushel, and so on down the scale, each succeeding scale indicating thedecreasing value of a bushel of wheat, or a moiety thereof, as itdecreases in test value.

In using the device, move the gage marked K, and which is movable,sliding on top ot' the scale, until the wire A is vertical to the numbercorresponding to the weight of the wheat. Then, the wheat having been'tested in the usual way and its grade determined, mark the same byplacing the movable plug a in the hole in the gage over the amount thatit tests, the gage being provided with rholes for that purpose, asshown. The number of pounds of i liour to be given to the customer forhis wheat will be shown opposite the plug and immediately under thewire. For example, take sixty pounds of wheat which tests fifty-eightpounds in grade or value, place the wire over the number in the scale A,place the plug in the hole immediately7 above the number 58 on the gage,and opposite this plug you will lind the number 3 7, indicating thenumber vof pounds of flour for the customer. If one hundred and twentypounds-of wheat are to be ground, the

gage will be forced over that number in the scale A, and the amount ofiiour to be given in exchange Will be readily designated, as shown. Anynumber of pounds of wheat may be so treated, it being understood thatthe squares upon the face of the device are all appropriately numbered,and the number of pounds of vflour to be given will he shown, derivingtheir quantity from the corresponding part ot' the gage. This rule andscale is made for taking one-tenth toll, giving thirty-nine pounds otliiour and twelve pounds ot' bran for full-test Wheat. In localitieswhere the law allows the miller a less toll than one-tenth, or more thanthat quantity, a similar scale can be made upon the same plan, onlyyrequiring the different scales to be varied to suit AthecircumstancesIThis scale will befound of great value inall custom or exchangetlouring-mills, as it saves the constant making ot' mathematicalcalculations. v

1t will be observed that not only does this device readily andautomatically indicate the number of pounds of iiour to be given for acertain number otl pounds ot wheat ot' a certain gradesay sixty poundsto the bushelbut it also indicates the number ot pounds of flourto begiven l'or aspecitcnumber of pounds of wheat of lower grades.

l. In a wheat scale or calculator, a plate having'a horizontal scale todenote the number ot' pounds ot' wheat, and a series of parallel scalesgraduated from side to side in a ratio to correspond with the horizontalscale, and from top to bottom in a ratio to denote the quantity of iourto be givenfor a given quantity of grain, as denoted upon the scale upona gage, K, having a vertical graduated scale to denote the quality ofthe wheat, in combination with said gage K, having the said scale andindicatingwire A', arranged at a distance from the edge of the gage toclearly show the figures on the plate, all constructed and arrangedsubstan tially as shown and described.

2. The'combination of the main scale A and series of parallel scales BC, 8vo., with the sliding graduated gage K, having holes and a wire A,and the pin a, as and for the pur poses set forth.
